Ok after the reset it went right once, but the next time the noise is turned on again ...
Now I try to fix the whole room, sockets, new cables, ferrite magnets ... Anyway I need longer cables so they are purchases to be made ..
I think it's interference problems ...
If this remains the case, I will have the helix changed with the guarantee.
In my music room, an attic, in the summer it is very hot (I have yet to install the air conditioner), could the helix be ruined by being in a room with 40 centigrade?
